Gmail Sponsored Promotions
GSP ads show up in a Gmail user’s “Promotions” tab. These ads could drive considerable consumer action when well targeted to email users. Once the user clicks on the ad, it opens out like a normal email and shows a brand’s offer.
The mail can be highly aesthetic, including images, a logo and a button with an encouraging call-to-action. This type of ad unit can utilise the traditional GDN targeting settings and is recommended to bolster Search or Display Remarketing campaigns.
